In this step-by-step guide, you’ll learn how to create a simple 3D model in SolidWorks and get started with the basics of sketching, extruding, and modifying a part.
Why Learn SolidWorks?
SolidWorks is used in automotive, aerospace, robotics, and manufacturing industries due to its:
✔️ Easy-to-use interface – User-friendly for beginners
✔️ Parametric modeling – Modify designs without redrawing from scratch
✔️ Powerful simulation tools – Test strength, heat resistance, and motion
✔️ Industry demand – Essential for engineering professionals and students
Step-by-Step Tutorial: Creating Your First 3D Model in SolidWorks
🔹 Step 1: Open SolidWorks and Start a New Part
1️⃣ Launch SolidWorks and select New Document
2️⃣ Choose Part and click OK
💡 Tip: SolidWorks has three default planes (Front, Top, Right). You will start sketching on one of these planes.
🔹 Step 2: Create a 2D Sketch
1️⃣ Click on the Sketch tab in the toolbar
2️⃣ Select the Top Plane and click Sketch
3️⃣ Use the Rectangle Tool to draw a basic shape
💡 Tip: You can adjust dimensions using the Smart Dimension tool to define accurate sizes.
🔹 Step 3: Convert 2D Sketch into 3D (Extrusion)
1️⃣ Click on Features → Extruded Boss/Base
2️⃣ Select the 2D sketch you created
3️⃣ Set the extrusion height (e.g., 50mm) and click OK
🚀 Congratulations! You just created your first 3D object in SolidWorks!
🔹 Step 4: Add Features (Fillets & Holes)
✅ Fillet (Rounded Edges)
- Go to Features → Fillet
- Select the edges and set a radius (e.g., 5mm)
✅ Hole Creation (Using Extruded Cut)
- Click Sketch → Circle Tool
- Draw a circle on the top face of your model
- Click Features → Extruded Cut to create a hole
🔹 Step 5: Save & Export Your Model
1️⃣ Click File → Save As
2️⃣ Choose SolidWorks Part (.SLDPRT) or STEP, IGES, or STL for 3D printing
💡 Tip: Exporting to STL allows you to use the model for 3D printing!
Bonus: Rendering Your Model for a Professional Look
Want your model to look more realistic? Use SolidWorks Visualize to apply materials, colors, and lighting effects.
1️⃣ Click on Render Tools → Appearances
2️⃣ Apply materials like metal, plastic, or glass
3️⃣ Adjust lighting and shadows for a realistic look
Conclusion
SolidWorks is an essential tool for mechanical engineers, designers, and students. By following this guide, you’ve learned how to create a basic 3D model using sketching, extrusion, and modifying features. With practice, you can design complex parts, assemblies, and simulations to improve your engineering skills.
